My upper lip and top philtrum bulge out and the top lip turns in a bit. Would a lip lift be better than regular lip flips?

I have a long philtrum which is about 20mm. I think it’s got a longer in the past few years both because of aging and because I have to use a mouthguard for my tmj. This makes my upper lip and top philtrum bulge out and thus the skin stretch and the top lip turn in a bit. I think this problem might mean that the same thing would happen with a lip lift and so a lip flip would be regularly. Is this right? Could I do regular lip flips forever? Or would a lip lift be better. Thanks.
